Stalling problems

[daniel240]

well, ive been trying to solve my stalling problems ever since i got my turbo on. the motor will stall if i put it in neutral or push in the clutch if its above about 2500, or basically anytime im driving above 2500-3000rpm and shift to neutral or push in the clutch, it dies and and its hard to start and i have to wait like 10-20sec. to start it. from what ive found and heard, this problem could be caused from a few things. 1. the bov return hose not angled in towards the turbo. 2. mafs too close to the turbo, (i heard its recommended to be 18''+ away from turbo) 3. idle too low. my bov is angled in pretty good, and a while ago i bumped the idle up to 1000rpm, and after that it worked fine, for a few weeks. but ive been working on my car for about a month now not driving it, and now its stalling again, but its idling at 1000. i dont know what the problem is. its just real annoying having to heel toe, it all the time to keep from stalling. does anyone else have any other suggestions or recomendations? i know there are a few others with this same problem. i was thinking of trying a blow through mafs setup and see if that would help. anyone with a blow through have this problem? thanks.

It can also be a boost leak. Check to make sure all your hose conections are tight. And by tight I mean use a wrench to tighten the hose clamps. A screwdriver will not get it tight enough to seal under boost.

[daniel240]

i double checked and im sure i dont have any leaks. i tighted every clamp. damn this is so frustrating, i spent the last hour adjusting the idle and it still keeps stalling. i got the idle at about 1200 now. even when i rev it up in neutral above about 3000 it will die, or drop to almost 0.

Is your BOV vented open or recirculated?

[daniel240]

i have it recirculated. i cannot think of anything else to do. im wondering if i changed my mafs to a blow through type, if that would help. this is so annoying.

[tony/ka24de]

I have the same problem, I'm trying to figure it out

[daniel240]

so bumping the idle up didnt work for you either? what kind of setup are you running, and where is your mafs?

[Structure240sx]

i have noticed with my wideband that when the revs drop the engine can run very lean. if i leave mine in gear then an o2% reading instead of an air/fuel ratio(basically air i think). if i drop it into neutral thenit can run lean and die or almost go to zero. luckily i have an safc that you can set the decerlation settings to fix this.

[daniel240]

hmm thats wierd. i figured it would go rich when you let off the throttle. at least that is what i think mine is doing. because when it dies it is hard to start. i ushually have to wait like 20seconds to start it back up.

[huguetpj]

I'm sure mine goes lean when I lift my foot of the pedal. I'm still trying to figure it out but I'm thinking maybe the ECU thinks I'm deccelerating and it cuts fuel and doesn't go into "idle mode". Maybe my TPS has issues.... still searching for an answer myself.

[daniel240]

maybe i could try disconecting the bov recirculating hose from the intake and see what that does. it would give it less air and would make it run a little more rich if it is leaning out. but i dont think that would help since running an nonrecirculating bov would ushually cause it to stall out. thats why i think its running rich.

[huguetpj]

If you're problem is like mine... it won't help... been there done that... but hell it never hurts to try

[JonnyB4Real]

has anyone figured this problem out yet?? Lots of people have this problem apparently and Im searchin for the solution.

[tony/ka24de]

I'm still having the same problem and can't figure it out.

[huguetpj]

Haven't had time to look into it. I'm taking on the several exhaust leaks I've got. Does somebody know where I can buy mechanical locking nuts online?

[tony/ka24de]

where are you bumping up your idle from?..... daniel240

[daniel240]

on the back of the intake man. w/ that small screw. And i still havent figured this problem out yet:mad:

[huguetpj]

Yep... it get's frustrating. But hell if eveything about turbos was written in rock we wouldn't have much fun... hehe. For example, I am now running an open BOV (was going to the beach and wanted to make some noise) and don't seem to be running rich between shifts... go figure.

[daniel240]

haha, man, i will be so glad when i get this problem fixed. its really not that big of a deal, its just so f##king annoying.

[huguetpj]

Nope... it's not that big of a deal... I just had to fix my starter cause the charcoal brushes where crap :pface

[tony/ka24de]

daniel there is a set screw on your throttle body. Adjusting that screw will hold the throttle plate open a bit more. This will bump up your idle and will solve your problem. I know its not the right way to do it, but it works.

[huguetpj]

Been there, done that. I bumped the idle to 1k rpm using the TB screw and the problem remained... but as I said it might work on other cars.

[daniel240]

where is this TB screw? please let me know, i want to try. and how do i adjust it. do i need to unplug the tps connector?

[huguetpj]

Wouldn't know, sorry. Mi mechanic did it while I was tinkering with other stuff.

[tony/ka24de]

no you don't have to unplug the tps sensor . The screw stops the peice that your throttle cables are connected to. Its at the bottom .

[daniel240]

so its by the throttle cable on the TB? sorry, i looked for it real quick but couldnt find it.

Mine also dies sometimes....

I just run the AC and it does not

[daniel240]

i have not tried that yet. i still want to fix it the right way though.

[huguetpj]

AC won't do it for me.... seems like I have a very bad case of stalling :pface

[Red-KAT]

Sorry I read you 1st post better...

Mine stalls and I have no bov... So mine is not that... Also mine never did this befor turbo so its not my idle...

I think the MAF being to close could be the issue... Now I want to move mine out farther to see if that works...
